The first house belongs to Sun according to vedic astrology. Saturn is not welcome in the first house. First house represents the physical and to certain point the emotional characteristics of the native. Saturn is rigid, slow, dominating and boring. He brings disaster, famine, oppression and everything that is unwelcomed by others. Naturally the person with Saturn in first house isn't the most popular person on the campus unless other friendly planets help.

     But if the native leaves the popularity contest aside Saturn is the best place in first house especially if it there is own sign, exalted or friendly sign in first house. Saturn bring discipline which is often confused with restrictions. Saturn loves following rules which is confused with boring personality. Saturn also loves boundaries set up by social norms which is often confused as rigid nature. As long as native learns not to force his view on others he/she would fare well in life. Saturn in first house helps craft an excellent and successful career for native through hard work and patience. Saturn loves slow and methodological approach and success comes late but that success is stable and secure.

     The only houses that stand to lose with Saturn in first house are the houses it casts an aspect on. That means equation with siblings, neighbours and ability to communicate with others could suffer via aspect on third house. Relationship with wife or business partner could also suffer via aspect on seventh house. Worst is relationship with employer, employees or co-workers at work place. But if there is a friendly sign in tenth house than career sees excellent progress even if Saturn does not have strength in first house.

     Saturn in first house is great for long term success and stability. It might cause troubles with siblings and business partner. Saturn can cause frictions with marriage partner but generally doesn't allow couples to separate.
